POWER-DRIVEN RAILWAY TRUCK.

Original application filed .Tune 24, 1925, Serial No. 39,353. Divided and this application filed April 20, 1926. Serial No. 103,289.

My invention relates to driving mechanisms, and it has particular relation to such mechanisms as are applicable to railway trucks.

Reference is herein made to my co-pending application, Serial No. 39,353, filed June 24, 1925, of which this application is a division.

One object of my invention is to provide a simple efficient drive for trucks, which is characterized by the absence of universal joints and complicated parts; by the ease of repair; and by its adaptability to present-day car trucks without necessitating material alterations in the same.

Another object of my invention is to provide means whereby the thrust of the driving element on the truck and car structure may be substantially neutralized.

A further object of my invention is to provide means whereby a proper working relation may be insured between the power device and the truck structure as the latter swivels relative thereto.

With these and other objects and applications in mind, my invention further consists in the details of construction and operation and arrangement, hereinafter described and claimed and illustrated in the accompanying drawings, wherein ig. 1 is a side elevational view of a car embodying my invention, wherein the primary source of power is a gas engine;

Fig. 2 is a detail elevational view, partially in section, of the slidable gearbox of Fig. 1 and mechanism directly connected therewith;

Fig. 3 is a plan view of the structure of Fig. 2;

Fig. 4 is a side elevational view, partially in section, of the structure of Fig. 3, and

Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 2.

Referring to Figs. 1 to 5, inclusive, a gas engine 129 is mounted on a forward end 131 of a car body 132. A transmission box 133 of usual design is pivotally mounted on bearings 134 and 135, which respectively support shaft sections 136 and 137. A driving shaft 138 extends between the gas engine 129 and the transmission box 133.

In accordance with my invention, the shaft section 136 is connected through a gear box or so-called power device 139 with a horizontally positioned crank disk 141. The crank disk 141 may be mounted on a swiveling truck 1'42, and it is operatively associated with a side bar 143 by means of connected vertical and horizontal shaft sections 141 and 142. J

The truck 142 is also provided with axles 143 and traction wheels 144" therefor. The power apparatus 139 comprises a. casing 144, which is mounted for longitudinal movement in ways 145 on the car body 132. Adepending The upper end of the vertical shaft 147 carries a bevel gear-wheel 155 which is adapted to mesh successively with bevel gear-wheels 156 and 157. The bevel gear-wheels 156 and 157 are mounted on an inner end 158 of. the shaft 136 and spaced by a sleeve 159. Bearings 161 and 162 serve to support the shaft end portion 158 immediately adjacent to the bevel gear-wheels 156 and 157, respectively, said bearings being mounted on a cover memher 163 slidably mounted on the casing 144.v

A hand wheel 164 is mounted on a shaft 165 which is journaled in bearings 166 and 167 carried by the cover member 163 and it is provided. with a threaded portion 168 which engages a nut portion 169 of said cover member 163. Collars 171 and 172 are spaced on opposite sides of the nut portion 169, so that when the hand wheel 164 is turned in one direction, the cover, member 163 is actuated to cause the bevel gear-wheel 156 to mesh with the bevel gear-wheel 155. When the hand wheel 164 is turned in the opposite direction, the bevel gear wheel 157 is carried tomesh with the main bevel gear-Wheel 155. Thus, the direction of rotation of'the shaft 147 may be controlled and hence the direc tion of movement of the truck 142.

When it is desirable to control substantially simultaneously the direction of operation of the shaft section 147 of the power device 139 and a corresponding shaft section 173 of a power device 174 (Fig. 1) the shaft is splined at 175 to a shaft 176 which is 7 adapted to move a cover member 177 and thereby control the direction of operation of the shaft 173 in the manner described above for the power device 139. The splined connection 175 between the shaft sections 165 and 176 permits such relative movement between the slidable power devices 139 and 174 as may obtain when the truck 1 12 swivels with respect thereto.

The bodily movable vertical shaft 173 is similarly associated with a side bar (not shown) on the opposite side of the truck 1 12, but in 90 relation to the side bar 143; As will be apparent, by connecting each power devicefto one side only of the truck 1 12, the lost motion of each unit is absorbed.

A compensating link 178, which is positioned in the swiveling plane of the truck 141-2, has one end pivotally mounted on the depending portion 1460f the slidable power device 139. T he other end isconnected to a bifurcated end portion 179 of a block 181 'lhus, the thrust bar 151 is neucompensating also pr the other power l he power devices 139 and 174 are hence retained by the compensating bars 178 and 182, respectively, in proper working relation to the truck 1452 as the latter swivels.

While I have shown one form of embodiment of my invention, for the purpose of de scribing the same and illustrating its principles of construction and operation, it is apparent that various changes and modifications may be made therein without departing from the spirit of my invention, and I desire, therefore, that only such limitations shall be imposed thereon as are indicated in the appended claims or as are demanded by the prior art.
